Access anchors.centerIn programatically

[SquimbellyToes]

Hello Folks;

I'm trying to do the following in a C++ class in which I programmatically create QQuickItems:

@
QQmlComponent vertexComponent(_engine, "../Resources/qml/MyItem.qml");
QObject *vObject = vertexComponent.create();
QQuickItem vQI = qobject_cast<QQuickItem>(vObject);
vQI->setProperty("anchors.centerIn", "parent");
...
@

However, I'm finding that I'm unable to set the anchors.centerIn property in this manner. In fact, I can find no way to access and set the anchors value through QQuickItem or the QMetaObject, as they seem to be private.

Might anyone know how I might be able to set anchors values from C++?

Thank you very much,
S.T.

I have the same problem now. Does anyone has a solution for it?

@PhTe I too had a similar requirement and ended up doing one of the following 2 ways

• Setting the anchors.centerIn: parent in the QML to be loaded itself. Make sure parent is set using setParentItem
  (See it here and here)
• Setting x and y properties after item creation. x and y can be calculated using its width and height according to parent's width and height.

QQuickItem *parent = view.rootObject(); //get parent item
QQmlComponent component(view.engine(),QUrl("qrc:/child.qml")); //load child item
QQuickItem *child = qobject_cast<QQuickItem*>(component.create());
child->setParentItem(parent);
child->setProperty("x",parent->width()/2-child->width()/2);
child->setProperty("y",parent->height()/2-child->height()/2);

The second point seems to be a good workaround.
